Investigation of stress distribution in rectangular plates with longitudinal stiffeners under axial compression after buckling

Chi-Teh Wang, Harry Zukerbergnaca-tn-2671Mar 1952

An investigation was carried out to study the elastic behavior after buckling of a rectangular plate reinforced with longitudinal stiffeners and subjected to compressive loads in a direction parallel to the stiffeners. Two possible buckling modes were investigated; namely, the plate may buckle around the stiffeners as nodal lines and edge stiffeners were assumed to have finite torsional rigidity, infinite bending rigidity perpendicular to the plate, and either finite or zero bending rigidity in the plane of the plate.
